plugin exiting with 127 code

[Stuart Browne]

Generally, checks will run as the 'nagios' user (nagios_user in nagios.cfg).  If the check needs to write to some temporary files, or is in a place where that user cannot read from, it may just be a 'Permission Denied' issue.

When you run it from the command line, do you run it as the 'nagios' user?

Subject: [Nagios-users] plugin exiting with 127 code

I think I have had this problem before and at that time it was a rogue
nagios process. But I have shut down nagios, inspected the process
list, ensured that no other nagios processes were still running, and restarted. And
the problem recurs. The plugin is definitely there and usually the
check passes with no problem. But sometimes it fails with this 127
code. I have run the test manually from the command line many times
and it never has a problem. Any idea what can cause this?
